Lasers interaction

Armor interaction​

A laser can interact with components, blocks, and entities.

A laser can also interact with entities (players or mobs) according to the plugin configuration. By default, it burns, damages and knocks back entities.

This laser/entity interaction can be modified using configurable armors. See armors page for more details.

Environmental interaction​

  • The laser is blocked by most physical blocks.
  • The laser will disappear if it stays too long in the air while orbiting around a gravitational sphere.
  • The laser will disappear if it leaves the puzzle area.
  • The laser will be filtered if it passes through a colored glass. See Glass and Glass Panes page or Colors page for details.

Diagonal edge and corner behavior​

When two or more solid blocks are placed corner-to-corner (diagonally adjacent, with no shared face), a laser traveling diagonally can encounter the edge or corner between them. The plugin detects these situations and applies the following rules:

  1. Clear path: If at least one intermediate block along the diagonal is crossable (air, flowers, glass panes, etc.), the laser passes through freely.
  2. Glass filtering: If any intermediate block is a stained glass block (full block, not a pane), the laser passes through but its color is filtered. When multiple glass blocks of different colors are present, their colors are merged before filtering. See Glass and Glass Panes for details.
  3. Mirror reflection: If all intermediate blocks are mirror blocks (concrete powder), the laser is reflected back (direction reversed), with color filtering applied. See Mirror block for details.
  4. Opaque block: Otherwise, the laser is stopped.

Note: Glass panes are treated as crossable at diagonal edges because they are thin (1/16 block width) and leave a physical gap.

Impact on other components​

  • It will activate a laser receiver if the colors match.
  • See Mirror page for specific interactions.
  • The prism will decompose the color if possible.
  • Conditional redstone block will be activated.
  • The concentrator will redirect the laser and recompose the color if possible.
  • Clay will melt.
  • The filtering sphere will filter the laser according to the mirror inside and the laser color.
  • The reflecting sphere will reflect the laser according to the mirror inside and the laser color.
  • A gravitational sphere will repulse or attract the laser if its is inside the sphere's range.
  • A laser hitting a portal from the front will be teleported to the linked portal, keeping its color, light level, and direction (transformed relative to the exit portal's orientation). See the Portal Gun page for details.
